Premise; A biased question survey.
Premise: A self-selected sample.
Conclusion: the conclusion is skeptica.
Inference: Since this si a Except quesion, the correct answer should express the information
that does not support the conclusion.
E: This is an irralavent answer, because whether NA are conerned with social issues has
no impact on the question between private finance and politics.


1:44 I need read slowly, and not repetition.
Premise: BC claims that there is no work for the work that is laying off.
Premise: BC is buying 100 new computers.
conclusion: hiring lower-paid workers is the reaons of laying off.
Inference: weaken.
In the first place, workers committed a fallacy of causal oversimplication.

The arugment of workes rests on a correlation between 100 new computers and hiring
lower-paid workers to establish a causality.

The line of reasoning is that because the company is buying 100 new computers,
hiring lower-paid workers is resposible for laying off.

However, the fact that the company is buying 100 new computers is not a good indicator
of recruiting lower-paid workers. It is possible that the new computers significantly  
improved the efficience of data-entry so that the company doesn't need so many data-entry
workers any more.

Thus, the resoning of worker is fallacious unless other possible explainations
have been concerned and ruled out.

E: If the current management and sales stuff can perform the work that data-etry workers
were previous doing, this evidence indicates that company doesn't need so many data-entry
resouces any more and eliminates the explaination of recuiting lower-paid wokers.

Premise: two computers have similar price and are equally easy to use.
Conclusion: Ap computer is likely to dominate the market
Inference: Ap computer has some advantage, which is quite attractive for market,
that Ga computer doesn't have.
E

Premise: the number of RDS radio station increased from 250 to 600;
Premise: the number of RDS-equiped radio was abou the same in 1996 as in 1994;
Conclusion: the number of people who receive speical program probably did not increase;
Inference: The argument rests on a causal assumption that there is a positive
corrdination between the number of people who receive special program and the number of
RDS-equiped radio, which means that the special program can only be transmitted by
RDS equipment.
D: people without RDS-equipped radio cann't receive any programming from RDS radio stations.
OK, D is just a repetition of the first sentence.A: few if any of 极少有, 即使有 也很少
If many people were not covered by Radio station in 1994, more radio station built in 1996 will cause more people receiving the Radio, thus this answer weakened the argument.



41
Premise: A situation indicates that a restaurant chain who want to rapidly increase their sales.
Premise: G wishes to achive continued sales growth rapidaly.
Conclusion: then you should open new restaruant at the same rates as in the last two years.
Inference: There is no more patrons to be drawn away from other restaurants in his vicinity.
D: So if you open your new resturant in the vicinity of your own existing resturants,
in accordance with the station, you won't draw patrons from other restaurants.

1. Statistician: A financial magazine claimed that its survey of its subscribers showed that North Americans are more concerned about their personal finances than about politics. One question was: “Which do you think about more: politics or the joy of earning money?” This question is clearly biased. Also, the readers

纠错：逻辑链第三题：本题运用双重否定来判断A 是正确的。

双重否定A之后的逻辑如下：
如果远程发送广播可以被接收的话，每增加一个广播站一定会带来收听人的递增（有点像抢地盘）。

然而A 选项的本来意思是广播只能就近被接收，而且广播站都建设在verdland范围内。所以人数增加有限是很正常的。

我的错误在于对分词翻译的不熟悉。我将结论理解成收到广播的数量没有显著增加了。应该是：收听广播的人数没有随广播站的数量增加而显著增加。


the explanation as follows is from sdcar2010: thanks for her help~~~
Necessary assumption. Use negation.

If you negate A), you have:

Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 DID NOT broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.

This is a double negative statement. If that is true, then almost all these stations broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations. In other words, stations reached out to NEW listeners! If so, the conclusion “the number of Verdlanders receiving the special program information probably did not increase significantly” is wrong. Thus, A) is the necessary assumption.
